I want to export the data in multiple sheets with multiple excel files. As you can see in my image I want to generate sheets as ID
changes and when ModalityId
changes I want to create new excel.
I have made code like this for this concern:
List<string> lstFile = new List<string>();
if (dtAltTag != null && dtAltTag.Rows.Count > 0)
{
string filePath = string.Empty;
string fileName = "";
Excel.Workbook workBook = new Excel.Workbook();
var workSheet = new Excel.Worksheet(fileName);
if (dtAltTag.Rows[0]["OldFormCode"] != null && dtAltTag.Rows[0]["OldFormCode"].ToString() != "")
{
fileName = dtAltTag.Rows[0]["OldFormCode"].ToString();
}
else
{
fileName = dtAltTag.Rows[0]["Code"].ToString();
}
workSheet.Name = fileName;
AddValue(0, workSheet, dtAltTag); // function is used to add the value in the sheet
workBook.Worksheets.Add(workSheet);
//data working
for (int i = 0; i < dtAltTag.Rows.Count; i++)
{
//for modality changes and first entery
//if (i == 0 || dtAltTag.Rows[i]["ModalityId"] != dtAltTag.Rows[i - 1]["ModalityId"])
//{
//if form changes then it should be in other sheet
if (i != 0 && dtAltTag.Rows[i]["ID"].ToString() != dtAltTag.Rows[i - 1]["ID"].ToString())
{
if (dtAltTag.Rows[i]["OldFormCode"] != null && dtAltTag.Rows[i]["OldFormCode"].ToString() != "")
{
fileName = dtAltTag.Rows[i]["OldFormCode"].ToString();
}
else
{
fileName = dtAltTag.Rows[i]["Code"].ToString();
}
var workSheet1 = new Excel.Worksheet(fileName);
AddValue(i, workSheet1, dtAltTag);
}
else
{
}
}
filePath = HostingEnvironment.MapPath(ConfigurationManager.AppSettings["ExcelFilesFilePath"]) + "Allitem";
if (!File.Exists(filePath))
Directory.CreateDirectory(filePath);
filePath = filePath + "\\" + fileName + "_" + DateTime.Now.ToString("MM_dd_yyy_HH_mm_ss") + ".xls";
workBook.Save(filePath);
lstFile.Add(filePath);
}
return lstFile;
When the id is changed I append new header but after that, I want to continue export data till the id change can't detect how to do this? How can I get the current sheet where I continue adding the value in else case?
I hope you are cleared of what I am trying to do!
Thanks in advance!
Can't you do it otherwise:
ModalityId
is different save current file and create a new one (assign it back to current file variable)ID
is different create a new sheet (append it to current file and assign it back to current sheet variable)That could be pseudo-code for it:
var currentFile = new ExcelFile();
var currentSheet = currentFile.AppendSheet(rows[0].SheetName);
string lastFileName;
for(int i = 0; i < rows.Count; i++)
{
// Adds new file if necessary
if(i != 0 && rows[i].ModalityId != rows[i - 1].ModalityId)
{
currentFile.Save(rows[i - 1].FileName);
currentFile = new ExcelFile();
}
// Adds new sheet if necessary
if(i != 0 && rows[i].ID != rows[i - 1].ID)
{
currentSheet = currentFile.AppendSheet(rows[i].SheetName);
}
InsertData(currentSheet, rows[i]);
lastFileName = rows[i].FileName;
}
currentFile.Save(lastFileName);
With the reference of 'Rafalon' code, I made some change in my code and its working fine ! thank You!
My code is as below:
var filePath = "";
string fileName = "";
if (dtAltTag.Rows[0]["OldFormCode"] != null && dtAltTag.Rows[0]["OldFormCode"].ToString() != "")
{
fileName = dtAltTag.Rows[0]["OldFormCode"].ToString();
}
else
{
fileName = dtAltTag.Rows[0]["Code"].ToString();
}
int Row = 0;
var currentFile = new Excel.Workbook();
var currentSheet = new Excel.Worksheet(fileName);
currentFile.Worksheets.Add(currentSheet);
List<string> lstFile = new List<string>();
if (dtAltTag != null && dtAltTag.Rows.Count > 0)
{
for (int i = 0; i < dtAltTag.Rows.Count; i++)
{
if (i == 0)
{
AddValue(i, currentSheet, dtAltTag, Row);
}
else
{
if (dtAltTag.Rows[i]["ModalityId"].ToString() != dtAltTag.Rows[i - 1]["ModalityId"].ToString())
{
filePath = HostingEnvironment.MapPath(ConfigurationManager.AppSettings["ExcelFilesFilePath"]) + "Allitem";
if (!File.Exists(filePath))
Directory.CreateDirectory(filePath);
filePath = filePath + "\\" + fileName + "_" + DateTime.Now.ToString("MM_dd_yyy_HH_mm_ss") + ".xls";
lstFile.Add(filePath);
currentFile.Save(filePath);
currentFile = new Excel.Workbook();
}
if (dtAltTag.Rows[i]["ID"].ToString() != dtAltTag.Rows[i - 1]["ID"].ToString())
{
if (dtAltTag.Rows[i]["OldFormCode"] != null && dtAltTag.Rows[i]["OldFormCode"].ToString() != "")
{
fileName = dtAltTag.Rows[i]["OldFormCode"].ToString();
}
else
{
fileName = dtAltTag.Rows[i]["Code"].ToString();
}
currentSheet = new Excel.Worksheet(fileName);
currentFile.Worksheets.Add(currentSheet);
Row = 0;
}
AddValue(i, currentSheet, dtAltTag, Row);
}
Row++;
}
filePath = HostingEnvironment.MapPath(ConfigurationManager.AppSettings["ExcelFilesFilePath"]) + "Allitem";
if (!File.Exists(filePath))
Directory.CreateDirectory(filePath);
filePath = filePath + "\\" + fileName + "_" + DateTime.Now.ToString("MM_dd_yyy_HH_mm_ss") + ".xls";
currentFile.Save(filePath);
lstFile.Add(filePath);
}
This function of adding value in sheet is might be useful:
private void AddValue(int i, Excel.Worksheet workSheet, DataTable dtAltTag, int Row)
{
//Header Working starts here
string[] columName = new string[] { "column1", "column2", "column2", "column2", "column2" }; //add header as per you requirement
if (Row == 0)
{
for (int c = 0; c < columName.Length; c++)
{
workSheet.Cells[0, c] = new Excel.Cell(columName[c]);
}
}
//add data
for (int c = 0; c < columName.Length; c++)
{
workSheet.Cells[Row + 1, c] = new Excel.Cell(dtAltTag.Rows[i].ItemArray[c].ToString());
}
}
